cdf

Compute cumulative distribution function values.

Syntax

p=cdf(dist,x,a)

p=cdf(dist,x,a,b)

Inputs

dist: The distribution name.; Type: string
x: Values of the distribution random variable.; Type: double; Dimension: scalar | vector | matrix
a,b: Distribution parameters.; Type: double | integer; Dimension: scalar

Outputs

p: Cumulative probability values.

Example

Vector example with normal distribution.

x = [1,2,3,4,5,6,7];
a = 5;
b = 3;
p = cdf('norm',x,a,b)

p = [Matrix] 1 x 7
0.091211 0.15866 0.25249 0.36944 0.5 0.63056 0.74751
